Abstract:

Surface segregation in metal oxides can greatly influence the oxygen transport and surface oxygen exchange kinetics critical to the performance of solid-state devices such as oxygen permeation membranes and solid oxide fuel/electrolytic cell electrodes. Unfortunately detecting elemental distributions at the atomic scale near the surface remains challenging, which hampers the understanding of underpinning mechanisms and control of surface segregation for the design of high-performance materials. Using the coherent Bragg rod analysis (COBRA) method, we report the first direct 3D atomic imaging of a 4 nm-thick “La0.8Sr0.2CoO3–δ”/SrTiO3 epitaxial film. Continue reading.

Researchers gained new insight into thin-film superiority by probing the structure of perovskites at the the U.S. Department of Energy's Advanced Photon Source (APS), Argonne National Laboratory. They used a groundbreaking approach to tease apart the thin-film structure and chemistry layer-by-layer. Continue reading.

Abstract:

New catalysts for the oxygen evolution reaction in basic solution are important for energy storage applications. Here, the authors report the high activity and stability of double perovskites in this role, and their performance is interpreted with regard to the proximity of the oxygen p-band to the Fermi level.

Watch a short movie of the catalyst evolving oxygen.

Highly active catalysts could be key to improved energy storage in fuel cells and advanced batteries.

Abstract:

In this Letter, we report the first in situ transmission electron microscopy observation of electrochemical oxidation of Li2O2, providing insights into the rate limiting processes that govern charge in Li–O2 cells. In these studies, oxidation of electrochemically formed Li2O2 particles, supported on multiwall carbon nanotutubes (MWCNTs), was found to occur preferentially at the MWCNT/Li2O2 interface, suggesting that electron transport in Li2O2 ultimately limits the oxidation kinetics at high rates or overpotentials.

Watch our movies of Li2O2 oxidation: movie 1, movie 2 and movie 3.

Imaging reveals what happens during charging; could lead to improved batteries for electric cars.

Warm welcome to our new visiting students Niels Bendtsen Halck, Roberta Verrelli, Ivana Hasa and our new undergraduate summer students Raivo Andrian, Julia O'Donnell, Alyssa Johnson and Joey Valle!

Roberta Verrelli is a student in Chemical Science at "Sapienza" University of Rome. My research is focused on the development of alternative electrode materials for higher performance lithium ion batteries. Her passion is to travel all over Europe.

Ivana Hasa is a student in Chemical Science at "Sapienza" University of Rome. She is involved in the field of the electrochemical energy conversion since her master studies. She played volleyball in a federal team for 12 years sharing victories and defeats. She also likes to cook good Italian food, especially cakes and pies.

Alyssa Johnson is a rising senior at the University of St. Thomas in St. Paul, MN, studying Mechanical Engineering. She is interested in electrochemical energy storage and conversion because she believes there needs to be a shift to cleaner energy sources. In her free time, she enjoys longboarding, snowboarding, and sketching.

Julia O'Donnell is originally from Iowa City, IA, and will be returning to Wellesley College to complete her physics degree this fall. She hopes her research in nanostructuring hematite for photoelectrochemistry will contribute to the eventual design of a low-cost device, which brings clean energy to the developing world. When not in the lab, she enjoys horseback riding, bicycling, and playing the harp.

Raivo Andrian is a sophomore in course 10 who enjoys running, eating dessert, and of course working with EEL. Her favorite kind of food is Indian food.

Niels Bendtsen Halck came to EEL from the University of Denmark to support the group with theoretical calculations (DFT) in its goal to design and understand catalysts for the oxygen evolution reaction. When he is not frustrated with non-converging calculations he likes to spend his time outdoors with his wife and dog.

MIT has listed Jens Nørskov’s group’s "CatApp" mobile app on a web site where they’re recommending apps as well as featuring it in an IAP seminar on useful apps. It is a mobile web app for looking up calculated reaction and activation energies for elementary coupling reactions occurring on metal surfaces. You can find it and many other useful apps listed under "Science & Engineering" at http://libguides.mit.edu/content.php?pid=174869&sid=1481866 It can also be found at http://suncat.slac.stanford.edu/catapp/. Learn more about it in the paper by Hummelshøj et al in Angewandte Chemie CatApp: A Web Application for Surface Chemistry and Heterogeneous Catalysis.
